游戏开发之路 二

开发Demo 一

1.角色功能

① 朝着鼠标点击方向转动：（Done）

    Vector3 Move_Player(){
        Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
        RaycastHit hitInfo;
 
        if(Physics.Raycast(ray, out hitInfo, 200, whatIsGround)){
            Vector3 target = hitInfo.point;
            target.y = transform.position.y;
            transform.LookAt(target);
            return target;
        }
        else
        {
            Debug.Log("error");
            return Vector3.zero;
        }
    }

②角色射击：（Done）

void Fire()
    {
        Vector3 shutdir;
        if (Input.GetMouseButtonDown(0))
        {
            bullet = (GameObject) Instantiate(Gamemanager.instance.bullet.bulletprefab,
                transform.GetChild(0).position, Quaternion.identity);
            shutdir = (Move_Player()-transform.position).normalized;
            bullet.transform.GetComponent<Shut>().ShutDir = shutdir;
        }
    }

③角色对Enemy造成伤害：（Done）

private void OnTriggerEnter(Collider other)
    {
        DamageData data=new DamageData();
        if (other.tag=="Enemy")
        {
            data.damage = Gamemanager.instance.bullet.Damage;
            get_hit_able getHitAble=transform.GetComponent<get_hit_able>();//get_hit_able 是否可以受伤的一个脚本
            if(getHitAble==null)return;
            getHitAble.OnDamage(data);
        }
        
    }

    //     }
        
    // }

④敌人AI移动：（Done）

if(Vector3.Distance(Target.position,transform.position)>=Attack_Area)
        {
            _navMeshAgent.SetDestination(Target.position);
            transform.LookAt(Target.position); 
        }
        else
        {
            if(State!="Attack")
            animator.SetTrigger("Attack");
            // State="Attack";
            // }
        }
